Experimental observation of exceptional bound states in the continuum
Shuang Wu, Ruizhi Dong, Nikolay Solodovchenko +3
We experimentally demonstrate second- and third-order exceptional bound states in the continuum (EP-BICs), formed by the merging of two and three symmetry-protected BICs at an exce…

Ultra-broadband acoustic ventilation barriers via hybrid-functional metasurfaces
Ruizhi Dong, Dongxing Mao, Xu Wang +1
Ventilation barriers allowing simultaneous sound blocking and free airflow passage are of great challenge but necessary for particular scenarios calling for sound-proofing ventilat…

Extremely asymmetrical acoustic metasurface mirror at the exceptional point
Xu Wang, Xinsheng Fang, Dongxing Mao +2
Previous research has attempted to minimize the influence of loss in reflection- and transmission-type acoustic metasurfaces. This letter shows that, by treating the acoustic metas…
